Quran on the protective sky - the protected roof

In the Qur'an, Allah calls our attention to a very important attribute of the sky:

We made the sky a preserved and protected roof yet still they turn away from Our Signs. (Qur'an, 21:32)

This attribute of the sky has been proved by scientific research carried out in the 20th century: The atmosphere surrounding the Earth serves crucial functions for the continuity of life. While destroying many meteors-big and small-as they approach the Earth, it prevents them from falling to Earth and harming living things.

In addition, the atmosphere filters the light rays coming from space that are harmful to living things. The most striking feature of the atmosphere is that it lets only harmless and useful rays-visible light, near ultraviolet light and radio waves pass through. All of this radiation is vital for life. Near ultraviolet rays, which are only partially let in by the atmosphere, are very important for the photosynthesis of plants and for the survival of all living beings. The majority of the intense ultraviolet rays emitted from the Sun are filtered out by the ozone layer of the atmosphere. Only a limited and essential part of the ultraviolet spectrum reaches the Earth.

The protective function of the atmosphere does not end here. The atmosphere also protects the earth from the freezing cold of the space, which is approximately -270oC.

It is not only the atmosphere that protects the Earth from harmful effects. In addition to the atmosphere, the Van Allen Belt-the layer caused by the magnetic field of the Earth-also serves as a shield against the harmful radiation that threatens our planet. This radiation, which is constantly emitted by the Sun and other stars, is deadly to living things. If the Van Allen belt did not exist, the massive outbursts of energy called solar flares that frequently occur in the Sun would destroy all life on Earth.

Blasts of particles and magnetic fields from the Sun impact the Earth's magnetosphere

 The magnetosphere layer, formed by the magnetic field of the Earth, serves as a shield protecting the Earth from celestial bodies, harmful cosmic rays and particles. In the above picture, this magnetosphere layer, which is also named Van Allen Belts, is seen. These belts at thousands of kilometres above the Earth protect the living things on the Earth from the fatal energy that would otherwise reach it from space.

All these scientific findings prove that the world is protected in a very particular way. The important thing is that this protection was made known in the Qur'an in the verse "We made the sky a preserved and protected roof" fourteen centuries ago.

On the importance of the Van Allen Belt, Dr. Hugh Ross says:

In fact, the Earth has the highest density of any of the planets in our Solar System. This large nickel-iron core is responsible for our large magnetic field. This magnetic field produces the Van-Allen radiation shield, which protects the Earth from radiation bombardment. If this shield were not present, life would not be possible on the Earth. The only other rocky planet to have any magnetic field is Mercury-but its field strength is 100 times less than the Earth's. Even Venus, our sister planet, has no magnetic field. The Van-Allen radiation shield is a design unique to the Earth.21

The energy transmitted in just one of these bursts detected in recent years was calculated to be equivalent to 100 billion atomic bombs, each akin to one dropped on Hiroshima at the end of World War II. Fifty-eight hours after the burst, it was observed that the magnetic needles of compasses displayed unusual movement and 250 kilometres above the Earth's atmosphere, the temperature suddenly increased to 2,500oC.

Most people looking at the sky do not think about the protective aspect of the atmosphere. They almost never think what kind of a place the world would be like if this structure did not exist. The photo belongs to a giant crater caused by a meteor that fell near the San Francisco mountains, in the USA. If the atmosphere did not exist, millions of meteoroids would fall to the Earth and the Earth would become an inhabitable place. Yet, the protective aspect of the atmosphere allows living things to survive in safety. This is certainly Allah's protection of people and a miracle proclaimed in the Qur'an.

In short, a perfect system is at work high above the Earth. It surrounds our world and protects it against external threats. Centuries ago, Allah informed us in the Qur'an of the world's atmosphere functioning as a protective shield.

 

 

 

ATMOSPHERIC LAYERS

Another fact about the universe also revealed in the verses of the Qur'an is that the sky is made up of seven layers:

It is He Who created everything on the earth for you and then directed His attention up to heaven and arranged it into seven regular heavens. He has knowledge of all things. (Qur'an, 2:29)

Then He turned to heaven when it was smoke. (Qur'an, 41: 11)

In two days He determined them as seven heavens and revealed, in every heaven, its own mandate. (Qur'an, 41: 12)


The atmosphere only lets rays required for life reach the Earth. For example, ultraviolet rays make it to the world only partially. This is the most appropriate range to allow plants to make photosynthesis and eventually for all living things to survive.

The word "heavens," which appears in many verses in the Qur'an, is used to refer to the sky above the Earth, as well as the entire universe. Given this meaning of the word, it is seen that the Earth's sky, or the atmosphere, is made up of seven layers.

 Today, it is known that the world's atmosphere consists of different layers that lie on top of each other.19 Based on the criteria of chemical contents or air temperature, the definitions made have determined the atmosphere of the earth as seven layers.20 According to the "Limited Fine Mesh Model (LFMMII)," a model of atmosphere used to estimate weather conditions for 48 hours, the atmosphere is also 7 layers. According to the modern geological definitions the seven layers of atmosphere are as follows:

1. Troposphere

2. Stratosphere

3. Mesosphere

4. Thermosphere

5. Exosphere

6. Ionosphere

7. Magnetosphere

 

 

The Qur'an says, "[He] revealed, in every heaven, its own mandate," in Surah Fussilat 12.

In other words, Allah is stating that He assigned each heaven its own duty. Truly, as will be seen in following chapters, each one of these layers has vital duties for the benefit of human kind and all other living things on the Earth. Each layer has a particular function, ranging from forming rain to preventing harmful rays, from reflecting radio waves to averting the harmful effects of meteors.

The verses below inform us about the appearance of the seven layers of the atmosphere:

Do you not see how He created seven heavens in layers? (Qur'an, 71:15)

He Who created the seven heavens in layers. (Qur'an, 67:3)

The Arabic word "tibaaq" in these verses, translated into English as "layer" means "layer, the appropriate cover or covering for something," and thus stresses how the top layer is well suited to the lower. The word is also used in the plural here: "layers." The seven heavens in layers, as described in the verse, is without doubt the most perfect expression of the atmosphere. It is a great miracle that these facts, which could not possibly be discovered without the technology of the 20th century, were explicitly stated by the Qur'an 1,400 years ago.
